ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 298,110, dated May 6,1884.

- Application filed February 5, 18H4. (No model.)

.To al] whom it may' concern.:

Be it known that I, CHARLES F. Monsn, of

Somerville, in the county of Middlesex and State of Massachusetts, \haveinvented certain Improvements in Roller-Skates, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, making part of this speciiication, in which-Figure 1 represents a pair of skate-rollers with their connecting-axleconstructed in accordance with my invention and applied to one of thebearings on the under side of a skate, one roller being in section andthe other in elevation. Fig. 2 is a perspective view of my axle; Fig. 3,a perspective of the adjustable journal which screws thereon. Fig: 4-represents the key by which .the said journal, when adjusted, is lockedupon the end of the axle. Fig. 5 is a perspective of one side of thebox, located in the wheel in which the axlejournal bears. Fig. 6 is anelevation of the other side ofthe said box. Figs. 7 and S are elevationsof the opposite sides of the outer face-plate, which holds the journal-box in place within the wheel. Fig. 9 is a view of one side ofthe inner face-plate, by which the journal is retained within thewheel-box. i Fig. 10 is a view of the opposite side of said inner plate.Fig. 11 is a section representing the lubricat ing-passages. Fig. 12 isa section through the spring-actuated pin for keeping the outerfaceplate in place; Fig. 13, an elevation of the inside of the wheelwith its box and plates removed. Fig. 14 is a view of the spannerwrenchwhich I employ in securing the parts together or in detaching them.

This invention relates exclusively to the construction and manner ofconnecting a pair of skate-rollers with their axle. The ordinary way ofsecuring such rollers is by the passage through the holes centrally madein the wooden rollers of an axle-bolt having a head at one endand a slotin the other for the reception of a bent retaining-wire. Thisconstruction is obj ectionable, for the reasons that the oil used forlubricating is free to escape outside through the central hole in theroller, and soils the dress of the skater. The dress also catchesagainst the projecting end of the axlebolt and its retaining-pin. Saidprojecting end and pin under one skate are liable to strike against thecorresponding portions of the axle under the other skate of the pair'onthe feet of the skater. The dirt is sure to accumulate around the axleand grind and wear away the bearing in the wheel, and enlarge the holetherein so rapidly that the axle and wheels play tod loosely on eachother, and it is difficult to remove the retaining Wireor pin when theparts are to be separated to clean them.

To overcome these objections is the purpose of my present invention,which consists in a wheel having a metal box for the reception of ajournal, which screws on a threaded end of the axle, and is lockedthereto by a key when adjusted, a smooth metal face-plate flush with theoutside of the wheel being employed to holdthejournal-box therein, andan inner faceplate to retain the journal within its box, by whichconstruction oil is entirely or in a great measure prevented fromescaping from the wheel. Y catch against. Dirt is precluded fromentering the journal-box,- the rattling of the parts avoided, thefriction reduced to' the minimum, and the wear readily compensated bythe ad; justable journal.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in which I have carried it out.

. In the said drawings, A represents a wooden roller, having acylindrical hole, a, passing centrally throughl it, Fig. 13, andprovided with an inner and an outer annular shoulder, b, the said holebeing for the reception of a journalbox,B, Figs. 1, 5, and 6, having aninner annular flange, c, of considerable diameter let into the innerface ofthe wheel, and for a smooth plate, G, Figs. 1, 7, and 8, fittedin flush with the outside ofthe wheel, the outside of the No projectionsexist for the dress to journal-box screwing into the turned-down portiond ofthe interior of the outer faceplate,

vC, by which means they are both retained in their proper positions inthe wheel.

e is a circular hole made through the outer face-plate, C, for thereception of a springactuated pin, f, located in a hole, g, in thecontiguous portion of the wooden roller A, when the hole e in theplateis brought in line with the pin after the plate has been turnedsufdciently to draw the j ournal-box B into the desired position in thewheel, the pin preventing IOO the revolution of the plate C and itsunscrewing and separation from the journal-box. The journal-box is alsoprevented from turning accidentally and unscrewing from the outerfaceplate, C, by headed pins Z1, which pass through the iange c ofthejournal-box B into holes t', made in theadjacent innersurface ofthewheel.

D, Fig. 2, is the axle, each end of which has ascrew-thread, k, eutthcren,over which turns a sweat-threaded hollow journal, Z, Fig. 3,previded at its inner end with an annular flange, on, which tits intoashouidered recess, a, of the journal-box, Fig. 5. rIhe outer end oftheaxie is provided with a rectangular notch, p, and the annular wall ofthe corresponding end et' the journal is also provided with two notches,q, ofsimilar width, diametrically opposite each other, the notches inthejournal and axle being for the reception of a key, r, Fig. 4, forlocking them together, when so adjusted as to bring` the inner side ofthe flange in ot' thejournal against the outer side et' an innerfaceplate, E, and cause the latter to abut against the contiguous end ofthe bearing G of the axle on the under side ofthe skate, the innerfaceplate, E, being provided with a number ot' slots, s, correspondingto those et' the headed pins l1, each slot having an enlarged portion,t, to admit el' the plate being fitted upon the flange m of thejournal-box, after which said plate is turned apartial revolution by ashort projection, a, till the plate passes under the heads ot' the pinsh, and a notch, e, in the periphery et' the plate is brought in linewith a spring-actuated pin, zr, located in a hole, x, in the innersurface of the wheel, and passing through ahole, y, in the fiange inofthejournal box, whereby thcinner plate is prevented from turning andthe wheel from being detached from its journal, the distance between thetwo inner tace-plates, E, corresponding to the distance between the endsof the axle-bearing G on the under side ofthe skate.

To lubricate the jou rnais ofthe axle, an oilpassage, s, is provided,said passage extending from the outside of the inner face-plate, E,through the tiange m of the journal-box B, through the latter to thejournal Z, whereby the lubricant is conducted to the surfaces,

where the greatest friction occurs, the outer end of the journal-boxbeing closed to preclude the escape of the same and soiling the dress ofthe skater.

To remove the parts, when the journals are to be adjusted to compensatefor the slight wear resulting by continued use, or for other purposes, Iemploy a Spanner-wrench, II, (of

the form seen in Fig. 14,) having two projections, 16, the longer one ofwhich enters the hole c in the outer plate, C, occupied bythe pin f,which is pressed in against the resistance of its spring, thuspermitting the plate to be unscrewed from thejournal-box, the innerfaceplate, E, being unlocked after pressing the spring-pin w out ofthenotch e.

The outer face-plate, C, may be provided with a central hole, and thejournal-box Z be lengthened, so as to extend therein; but in such casethe outer surfaces ot' both would be continuously smooth and flush witheach other to avoid the existence ot' objectionable projections.

I claiml. An axle, D, having screwthreaded ends,

journals Z, capable of adjustment thereon, and

a means ot' locking them thereto, in combination with a pair et'rollers, A, having journalboxes B, and a means of securing them therein,constructed to operate substantially as and for the purposes described.

2. An axle, D, having its ends provided with screw-thrczuls k andnotches p, in combination with notched journals Z, adjustable thereon,and keys r, for locking them thereto, as set forth.

3. A roller, A, having ajournal-box, B, and an outer face-plate, C, forretainingit/therein, an axle, D, having screw-threaded ends, a journalcapable of adjustment thereon, and an inner faceplate, E, for lockingthe. roller upon the journal, as and for the purp0-c specified. \Vitnessmy hand this 31st day of January, 188i.
